A simulation method was proposed to predict the slippage and transversal vibration of the accessory drive belt. To reproduce these phenomena, the accessory drive belt was represented by a section-by-section model in which the belt was replaced by a finite number of masses and springs using multi-body dynamics simulation. In this model, the belt was able to vibrate in both the direction of advance and the direction perpendicular to it, and a friction contact element was defined between the pulley and the belt. The coefficient of friction was made variable with respect to the slippage speed to enable stick and slippage to be predicted. This method allows for accurate simulation of the amount of belt slippage and the amplitude of transversal vibration, thus enabling the optimum belt layout to be determined at the design stage.

In order to fulfill the requirement of vehicle dynamics performance and real-time capability in driving simulator, modeling and simulation method of a four-wheeled vehicle model based on multi body dynamics software Vortex was studied. Fundamental construction and dynamics properties of the model such as body, chassis, wheels, power train, suspension and tyre model were described. The model was tested to simulate on the C grade of road. The results indicate that the model and simulation method can well represent vehicle dynamics performance and high real-time capability of simulation, and is worthy to apply to driving simulator in the future.

Based on the V-type diesel engine crankshaft system, the paper combined the finite element method (fem) and multi-body dynamics method together, made a virtual simulation analysis. First, by 3d software and finite element software to establish the multi-body dynamic models of the crankshaft, bearing and piston, then simulated the actual engine working condition, and got the data such as crankshaft acceleration, velocity and displacement by the multi-body dynamics simulation analysis. By calculation, the paper found that by using the combination of finite element and multi-body simulation method, can we effectively simulate the diesel engine crankshaft dynamics characteristics.

For the problem that car sub-frame constraint connection complex and effective load more difficult to determine, using finite element and multi-body dynamics ADAMS co-simulation method, Analyzed on a Volkswagen vehicle sub-frame, obtained the accurate load on the sub-frame which are used by engine suspension. The finite element analysis results show that engine load is the greatest impact on the sub-frame stress field, which can be reduced by increasing the area of engine and the sub-frame contacting, thereby prolong the life of sub-frame.

It is worthwhile to design a more accurate dynamic model for air springs, to investigate the dynamic behaviour of an air spring suspension, and to analyse and guide the design of vehicles with air spring suspensions. In this study, a dynamic model of air spring was established, considering the heat transfer process of the air springs. Two different types of air spring were tested, and the experimental results verified the effectiveness of the air spring model compared with the traditional model. The key factors affecting the computation accuracy were studied and checked by comparing the results of the experiments and simulations. The new dynamic model of the air spring was integrated into the full-vehicle multi-body dynamics model, in order to investigate the air suspension behaviour and vehicle dynamics characteristics. The co-simulation method using ADAMS and MATLAB/Simulink was applied to integration of the air spring model with the full-vehicle multi-body dynamics model.

Misalignment on sun gear in planetary gear is easily occurred and it usually causes serious problem of work efficiency and lifetime with the change of planet load sharing. For study on the influence of sun gear misalignment on load sharing, multibody dynamics simulation is employed in this paper. First of all, 3D geometry model of planetary gear is built by Solidworks. Based on 3D model, multi-body dynamics model of planetary gear is built by MSC.ADAMS and calculate meshing forces between sun gear and planet gears with each type of sun gear misalignment which are angular, radial and axial type. Based on this meshing force result, load sharing factor is calculated and the results of influence of each misalignment type to load sharing factor is obtained. Finally, gear lifetime is estimated by AGMA gear fatigue strength estimation method with load sharing factor. According to the results, radial misalignment is the most influence to load sharing factor and gear lifetime.
